Some see this dress as white and gold. I, personally, see blue and black. And battle lines are being drawn. http://www.businessinsider.com/white-and-gold-black-and-blue-dress-2015-2 But if you see blue and black, congratulations!, your eyes are superior! Blue and Black: In conclusion, your retina's cones are more high functioning, and this results in your eyes doing subtractive mixing. —White and Gold: our eyes don't work well in dim light so our retinas rods see white, and this makes them less light sensitive, causing additive mixing, (that of green and red), to make gold." Even the Machines (ie. Google) think it's blue and black, so therefore it might be a test by them for the eventual machine uprising http://www.businessinsider.com/google-says-dress-is-black-and-blue-not-white-and-gold-2015-2 Anyway, yeah, blue & black.
